And the first line of the comments says it all. It DOES happen, and with every brand. Good luck with your 15!
The dealer treated me well. They didnt really want to believe the 4.3 EcoTec was going south at first. I took it in at 2,000, 4,300 and the final 8,043 miles. It developed a bad lifter knock at 2,000 miles when it was warming up but even at the end I towed my boat with it and it still ran hard.
The EcoTec has a dual pressure oil pump. One is low pressure high volume and at around 3,700 rpm's it goes to a high pressure side. It has 2 metal lines coming from it and the seal on the high pressure side was folded over on its self so when it when to the high pressure side it was dumping oil back in the pan. The top end of the motor was coked up and the valves were trashed. The dealer payed my truck payments while they had it and a month later got me in a 2015 with a 10k rebate just for my trouble. I cant complain. I got a Crew Cab V8 LS for less than I payed for the work truck V6 powered extended cab
